Antigua, the largest of the English-speaking Leeward Islands, is about 23 km long and 18 km wide, encompassing 280 square kilometres. Its highest point is Mount Obama (402 m), formerly known as Boggy Peak, located in the southwestern corner of the island. Barbuda, a flat coral island with an area of only 176 square kilometres, lies approximately 48 km due north. The nation also includes the tiny (1.6 square kilometre) uninhabited island of Redonda, now a nature preserve. Antigua has a deeply indented shoreline with many natural harbours and beaches and Barbuda has a large western harbour. Temperatures generally range from 20°C to 35°C. Annual rainfall averages only 1,140 mm, making it the sunniest of the Eastern Caribbean Islands, and the northeast trade winds are nearly constant.
Approximately 99,175 people live on both islands. People are referred to as Antiguan or Barbudan. English is the official language with Antiguan creole also spoken. Currency used: Eastern Caribbean Dollar (ECD) and US Dollar.

The Leeward Islands area is the most seismically active zone in the Eastern Caribbean and has hosted the largest magnitude earthquakes to have occurred in the region since the 1600’s, when written accounts for the region began. The average number of background earthquakes, i.e. those that recur on a daily/weekly basis, does not change drastically. The output level sometimes increases in association with the occurrence of a significant magnitude earthquake. This can take the form of foreshocks and aftershocks or only aftershocks. Since 2011, activity in the area has been generally elevated over that seen in previous years. Elevated activity is sometimes precursory to more significant magnitude earthquakes.
